xile Posted April 29, 2004 Report Share Posted April 29, 2004 I've been working on this for a couple of weeks, but I've tried everything I can think of for now.I'm using the MidiboxLC application with 2 2x40 CLCD displays. Host program is Sonar, but I had the same result with a friend's PC using Cubase.Also, I'm using the Sonar patch to the lc_mproc.inc file referenced in the topic "Midibox LC and Sonar Question".I have tested the 2 LCDs and they appear to be working correctly. I've tried the sysex commands that allow writes to the screen and they work. I've also tried version commands:f0 00 00 66 14 13 f7... and I get the proper response.I've even written gibberish to the LCD using the MTC Write command:f0 00 00 66 14 10 ..... f7However, from what I can tell, the midibox is not responding to the Write_LCD command:f0 00 00 66 14 12 .... f7There are definately changes in the Sonar mod file, lc_mproc.inc, that appear to relate to this command that are not in the file in 1.4 MidiboxLC distribution. Unfortunately, when I modify the Sonar mod file to match the original except for the MC Query addition, the file won't compile properly.Also, I tried the GPC mode and MF Cali mode and the display seemed to work fine.Also, I had another problem early on that related to the lc_init.inc file. I believe the line:#if LCD_USE_SECOND... should read:#if LCD_USE_SECOND == 1... in order to get the 2 LCDs to display properly. How do I get this suggestion checked out and the file changed if necessary?Thanks.xile Quote Link to comment Share on other sites More sharing options...
TK. Posted April 29, 2004 Report Share Posted April 29, 2004 Hi,the result of#if LCD_USE_SECONDand#if LCD_USE_SECOND == 1is the same, so this cannot be the reason.The only changes of the modified lc_mproc.inc and the original lc_mproc.inc of v1.4 are: [avatar@britannia mblc_sonar_mod]$ diff -c /mnt/data/mios_apps/release/midibox_lc_v1_4/lc_mproc.inc lc_mproc.inc *** /mnt/data/mios_apps/release/midibox_lc_v1_4/lc_mproc.inc 2003-09-29 14:22:28.000000000 +0200 --- lc_mproc.inc 2004-03-29 01:43:07.000000000 +0200 *************** *** 360,365 **** --- 360,369 ---- bz LC_MPROC_Action_Query movf LC_MPROC_ACTION, W + xorlw 0x1a + bz LC_MPROC_Action_MCQuery + + movf LC_MPROC_ACTION, W xorlw 0x02 bz LC_MPROC_Action_HostReply *************** *** 373,379 **** movf LC_MPROC_ACTION, W xorlw 0x12 ! bz LC_MPROC_Action_WriteLCD movf LC_MPROC_ACTION, W xorlw 0x13 --- 377,384 ---- movf LC_MPROC_ACTION, W xorlw 0x12 ! skpnz ! rgoto LC_MPROC_Action_WriteLCD movf LC_MPROC_ACTION, W xorlw 0x13 *************** *** 427,432 **** --- 432,463 ---- rgoto LC_MPROC_ActionFinished ;; -------------------------------------------------------------------------- + ;; MIDI Action: MC Query (undocumented) + ;; -------------------------------------------------------------------------- + LC_MPROC_Action_MCQuery + ;; wait until sysex footer (F7) has been received + movlw 0xf7 + IFNEQ LC_MPROC_IN, ACCESS, rgoto LC_MPROC_SysExCheck_End + + ;; send SysEx header + call LC_MPROC_Send_SysExHeader + + ;; send reply + movlw 0x1b + call MIOS_MIDI_TxBufferPut + + ;; send dummy byte (seems to work) + movlw 0x42 + call MIOS_MIDI_TxBufferPut + + ;; send of SysEx footer + movlw 0x01 ; (independend from merger state) + call LC_MPROC_Send_SysExFooter + + ;; finish Action + rgoto LC_MPROC_ActionFinished + + ;; -------------------------------------------------------------------------- ;; MIDI Action: LC Host Reply ;; -------------------------------------------------------------------------- LC_MPROC_Action_HostReply so: the new LC_MPROC_Action_MCQuery and a change for the LC_MPROC_Action_WriteLCD branch (distance between the "bz" and the function was > 128 bytes, therefore a rgoto has to be used).It should work if you just overwrite the old lc_mproc.inc with the modified one. Maybe you've modified the source code in a way which prevents the LC_MPROC_Action_WriteLCD function from being called...Best Regards, Thorsten.

djsegler Posted April 30, 2004 Report Share Posted April 30, 2004 So, to make one of these work with Sonar, theres a recompile involved?Any chance of updating the code that needs to be flashed (or downloaded) that's available directly from the site?I haven't gotten familiar enough with the code yet to tackle a re-compile!

xile Posted April 30, 2004 Author Report Share Posted April 30, 2004 I'll help you once I get a working config. I'm about to start over with a clean build based on Thorsten's feedback.We'll get Sonar working with the Midibox LC!xile Quote Link to comment Share on other sites More sharing options...
xile Posted May 3, 2004 Author Report Share Posted May 3, 2004 Well, the host messages are now displaying properly. I started over with a clean build, but that wasn't the problem. It turns out that that combination of MidiOx and my USB midi interface seem to be the problem. When I bypassed MidiOx, the USB interface would work, even though it wasn't perfect all the time. I have another midi interface and it's working properly, even with MidiOx.xile Quote Link to comment Share on other sites More sharing options...
